DOI: 10.1007/s12040-018-0969-5
Abstract: Precambrian magmatism in the Biabanak-Bafq district represents an extensive sequence of mafic magmatic rocks. Major, trace and rare earth elements reveal that the low-Ti basement mafic rocks are magnesium tholeiite and low-Ti cover a mafic… read more here.

DOI: 10.1016/j.gr.2017.12.001
Abstract: Abstract Understanding how Large Igneous Provinces (LIPs) formed in the Proterozoic is subject to several challenges, including incomplete geological exposure, deformations from subsequent reworking and the lack of strong geophysical signals from the associated thermal… read more here.

DOI: 10.1016/j.lithos.2016.12.030
Abstract: Abstract A dry mafic dyke from a continental lower-crustal shear zone in the Seiland Igneous Province (northern Norway) experienced syn-kinematic melt-rock interaction. Viscous shearing occurred at T ≈ 800 °C, P ≈ 0.75–0.95 GPa and was coeval with infiltration of felsic… read more here.

Crustal contamination versus an enriched mantle source for intracontinental mafic rocks: Insights from early Paleozoic mafic rocks of the South China Block
Sign Up to like & getrecommendations! Published in 2017 at "Lithos"
DOI: 10.1016/j.lithos.2017.06.023
Abstract: Abstract Several recent studies have documented that the silicic rocks (SiO 2 > 65 wt.%) comprising Silicic Large Igneous Provinces are derived from partial melting of the crust facilitated by underplating/intraplating of “hidden” large igneous province-scale basaltic… read more here.
